Thanks, Chinze. This whole vapor lock issue is puzzling to me. Chrysler had decades of experience designing fuel systems when my car was built in the fall of 1973. Didn't they think about hot idling issues? They sold millions of vehicles and a helluva lot of slant six engines in hot environments, so they should have designed this issue out of the final products that they sold. How could they still have these vapor lock problems after all these years and billions of miles on their cars?
